SIG Sauer SOW45001 Whiskey4 5-20x50 FFP MOA Hunting Scope 2.0

The SIG Sauer Whiskey4 5-20x50 FFP MOA hunting scope delivers the precision and durability modern hunters need across varied hunting conditions. Built on SIG's proven optics lineage, this front focal plane riflescope combines a 4:1 magnification range with tactile, repeatable adjustments—so whether you're glassing at first light or taking a long-distance shot when adrenaline is high, you can trust your zero and your hold-over. The 5-20x magnification and 50mm objective lens balance light gathering with a practical field of view that works for everything from timber hunting to open-country glassing.

What sets the Whiskey4 apart is the attention to hunters' real-world needs. The removable magnification throw lever gets out of the way when you don't need it, while the locking zero-stop elevation turret eliminates the guesswork of dialing up from a hard stop. The MOA Milling Hunter 2.0 reticle in the first focal plane means your hold-overs and windage holds remain true at any magnification—crucial for accurate long-range shots. Flip-back lens covers ship with the scope, keeping your glass protected without sacrificing quick access when game appears.

Inside, argon gas purging maintains optical clarity and seals out fog and water; the scope is rated IPX 6 for waterproofing. At 22.6 ounces on a 30mm maintube, the Whiskey4 balances heft with shooter control. The generous eye relief—3.5 to 3.9 inches—lets you shoot comfortably from a variety of rifle platforms, and the ±2 diopter adjustment range helps dial in your vision clearly. With over 52 MOA of total elevation and windage travel, you'll have room to dial for distance or correct for elevation and wind without running out of turret.

This is a scope built for hunters who demand reliability and intuitive operation when it counts.

Frequently Asked Questions

What hunting situations is the 5-20x50 magnification range best suited for?

The 5x low magnification works well for close-to-medium range hunting in timber or brush, where a wider field of view helps track moving game. Crank to 20x for open country or long-distance shots where precise target acquisition and hold-over accuracy matter. The 4:1 ratio gives you flexibility across seasons and terrain without sacrificing usability at either end.

How does front focal plane design affect my shooting?

In a front focal plane scope, the reticle grows and shrinks with magnification, so your hold-overs and windage corrections stay true at any magnification setting. This is invaluable if you dial up to verify a distant target, then back down to shoot—your aim points don't shift. The MOA Milling Hunter 2.0 reticle is calibrated for this behavior, ensuring consistent ballistic holds from 5x to 20x.

What does the locking zero-stop elevation turret do?

Once you establish your zero by returning the elevation turret to its mechanical stop, the locking feature prevents accidental downward rotation. You can dial up for distance with confidence, knowing that if you accidentally bump the turret during hunting, you won't lose zero—just rotate back down to that locked stop and you're good to go.

Is this scope sealed against weather?

Yes. The scope is argon gas purged (sealed internally against humidity and fog) and rated IPX 6 for waterproofing, meaning it will withstand rain and wet field conditions. The factory-installed flip-back lens covers provide additional protection for the objective and eyepiece when you're moving through brush or in your pack.
